Description
Technical field
The utility model relates to the sterilization disinfection purifying device of room air, especially for the device of the bactericidal purifying that carries out disinfection in the central air-conditioning air exchange system.
Background technology
The central air-conditioning air exchange system of public place, in order to save the energy, reduce energy loss with door and window in the close chamber on the one hand, carry out recycling to room air exactly on the other hand, though central air-conditioning is provided with scavenge port, but be limited in the ventilation volume about 30%, 70% of indoor storage air is still and is recycled repeatedly.And the pollution level of room air than outdoor air serious 2～5 times, people on average have the time more than 80% to spend indoor, so IAQ is the key of health of people.Central air-conditioning makes room air muddy more, both to the human body discomfort, is again the environment that harmful bacteria, virus are grown.How to eliminate germ, the infective virus of room air, purify the air of a room, traditional disinfection way, for example medicine is smoked, steaming, liquid medicine are sprayed, all there is certain limitation in ultra violet lamp.CN1310316A proposes a kind of central air-conditioning compound efficient air purifier, is to carry out multiple times of filtration with screen pack, purifies air with anion generator, eliminates peculiar smell, avoids air conditioner disease.Though it can improve the quality of air, cause air quality inferior but still can't resolve central air-conditioning, the problem that harmful bacteria, virus spread procreation are grown.
Summary of the invention
The purpose of this utility model is to adopt multiple physical method to be combined into comprehensive disinfection system, improves the effect and the air purity of the overall sterilization of central air-conditioning air exchange system, reaches the purpose that improves IAQ.
The utility model adopts following technical scheme to realize above-mentioned target.
Central air-conditioning air sterillization sterilization purification device comprises it is characterized in that the backwind tube and the discharge pipe of air circulation system, the disinfection sterilization device of being made up of adjustable ozone generator in the meet setting of backwind tube; On the air-return duct of the front-end and back-end of ozone generator, establish the sterilization screen pack of forming by metal nano material or imidazoles sterilization material; Disinfection sterilization device again and the anion generator of being made up of the high-voltage corona pole plate is set in discharge pipe.
Said ozone generator can be that one group of pottery ozone generator is formed, and also can be one group of glass ozone generating pipe, can also be to be combined by ceramic ozone generator and glass ozone generating pipe.Every group of ozone generator sterilization period ozone amount is at 5～10ppm, and purifying the period is the above ozone amount of 0.15ppm, and every group of composite design foundation is to decide according to sterilizing and purifying space size.
Described screen pack is by containing the airstrainer that the sterilization thing is formed, and as the efficient composite screen pack of nano phase ag_2 o or titanium oxide etc., the Econazole and the high molecular foam material that perhaps contain pyrrole leaf amide structure are formed screen pack.
Described high-voltage corona pole plate is made up of positive and negative electrode plate and high voltage source, the needle-like prickle that the two sides of positive electrode plate evenly is provided with, and negative plate is a conductive metal sheet, and high voltage electric field voltage is 30KV～250KV, and power is 100～200W.
The characteristics of said structure be the multiple physico-chemical process of comprehensive utilization to the circulating air of central air conditioner system sterilize, sterilization and purified treatment.At first be ozone generator, utilize the high-tension electricity field energy, fully activate oxygen molecule ionization in the air, produce positive and negative oxonium ion after moment be combined into ozone molecule and active anion, its can killing bacteria, virus, the oxidation pernicious gas, this is a disinfection for the first time.When air passes through by metal nano powder or macromolecule sterilization material screen pack, because nano phase ag_2 o or titanium oxide itself have extremely strong oxidation virus and the performance of bacterium, the Econazole of pyrrole leaf amide structure also is a kind of organic molecule material of high-effective disinfecting sterilization.Air enters the heat exchanger of air-conditioning system after by 2 sterilizations, when becoming hot-air or cold air through the discharge pipe leading portion by the high-voltage corona electric field, because the corona voltage across poles is more than 30000 volts, electric-field intensity is big between both positive and negative polarity, the negative ions that is ionized is many, and energy is big, other grains that suspend in major part and biological organic molecule and the air, pernicious gas generation oxidation, this is that the 3rd disinfection purifies, also the active anion of nonresident portion is assigned in the turnover pipe of each branch with air outlet, improve anion concentration in the circulating air, meet the IAQ standard to reach.
